Abstract

The invention, which belongs to the intelligent device field, discloses an input device and an electronic device. The input device is composed of a processing unit and a plurality of transceiver units arranged in an array. The transceiver units are used for transmitting ultrasonic waves and receiving reflected ultrasonic waves, wherein ultrasonic wave transmitting directions of the plurality of transceiver units are parallel to each other. The processing unit is used for generating an input signal according to at least one of a time difference between time of transmitting an ultrasonic wave by each transceiver unit and time of receiving an ultrasonic wave by each transceiver unit and a strength difference between the strength of transmitting an ultrasonic wave and the strength of receiving an ultrasonic wave. The user does not need to carry out touching operation during the whole process and only the finger of the user is needed to be at an ultrasonic wave transmitting path; and thus a problem that the touch function can not be realized without touching is solved.

Description

technical field [0001] The invention relates to the field of intelligent equipment, in particular to an input device and electronic equipment. Background technique [0002] With the development of smart phones, the touch function has become one of the indispensable functions of smart phones. At present, the touch function mainly includes two parts: touch button instruction and fingerprint recognition. The touch function is usually designed as a touch button or integrated on the touch screen. When the user touches the touch button or the touch screen with a finger, an electrical signal is generated. The corresponding touch button instruction or user fingerprint image can be determined. [0003] However, such a touch function requires a user to perform a touch operation, and if the user does not perform a touch operation, an electrical signal cannot be generated, and thus the touch function cannot be realized. Contents of the invention [0004] In order to solve the proble...
